摘要： PROBLEM TO BE SOLVED: To improve the safety and prevent a wasteful gas consumption by opening the plug of a gas passage only when gas is used and measuring the instantaneous quantity of flow and opening the gas passage only when the gas is used and to prevent a wasteful electric power consumption by measuring the instantaneous quantity of flow only when the gas is used.
SOLUTION: When a control means 2 detects a signal from a pressure varying means 9 while the plug 3 is closed, the control means 2 determines that gas use is started, outputs an opening signal, and simultaneously transmits a measurement start signal to an instantaneous flow quantity measuring means 1 to start measuring the quantity of flow. At the reception of the opening signal, a valve opening drive means 4 outputs a valve opening drive signal to the valve 3 to make the valve 3 open the gas passage. In the case that the gas use is halted, a flow halting determining means 7 outputs a signal to the control means 2. The control means 2 outputs a closing signal, and simultaneously transmits a measurement halting signal to the instantaneous flow quantity measuring means 1 to halt the measurement of the quantity of flow. At the reception of the closing signal, a valve closing drive means 5 outputs a valve closing drive signal to the valve 3 to make the valve 3 close to the gas channel, thereby opening the gas passage only when the gas is used.
